If a\Large a and b\Large b are positive, which expression is equivalent to a8b124\Large \sqrt[4]{a^8 b^{12}}?

Divide each exponent by 4\Large 4: a84b124=a2b3\Large a^{\tfrac{8}{4}} b^{\tfrac{12}{4}} = a^2 b^3.

If m\Large m and n\Large n are positive, which expression is equivalent to m10n155\Large \sqrt[5]{m^{10} n^{15}}?

Divide each exponent by 5\Large 5: m105n155=m2n3\Large m^{\tfrac{10}{5}} n^{\tfrac{15}{5}} = m^2 n^3.

If x\Large x and y\Large y are positive, which expression is equivalent to x10y8\Large \sqrt{x^{10} y^8}?

A square root divides each exponent by 2\Large 2: x102y82=x5y4\Large x^{\tfrac{10}{2}} y^{\tfrac{8}{2}} = x^5 y^4.

If p\Large p and q\Large q are positive, which expression is equivalent to p18q126\Large \sqrt[6]{p^{18} q^{12}}?

Divide each exponent by 6\Large 6: p186q126=p3q2\Large p^{\tfrac{18}{6}} q^{\tfrac{12}{6}} = p^3 q^2.

If r\Large r, s\Large s, and t\Large t are positive, which expression is equivalent to r21s14t77\Large \sqrt[7]{r^{21} s^{14} t^7}?

Divide each exponent by 7\Large 7: r217s147t77=r3s2t\Large r^{\tfrac{21}{7}} s^{\tfrac{14}{7}} t^{\tfrac{7}{7}} = r^3 s^2 t.

Mid-gamemedium

If u\Large u, v\Large v, and w\Large w are positive, which expression is equivalent to u15v9w63\Large \sqrt[3]{u^{15} v^9 w^6}?

Divide each exponent by 3\Large 3: u153v93w63=u5v3w2\Large u^{\tfrac{15}{3}} v^{\tfrac{9}{3}} w^{\tfrac{6}{3}} = u^5 v^3 w^2.

Mid-gamehard

If a\Large a and b\Large b are positive, which expression is equivalent to a5b64\Large \sqrt[4]{a^5 b^6}?

Divide each exponent by 4\Large 4: a54b64=a54b32\Large a^{\tfrac{5}{4}} b^{\tfrac{6}{4}} = a^{\tfrac{5}{4}} b^{\tfrac{3}{2}}.
