## anonymous one year ago Which of the following is the simplest form of this expression? 5sqr(a^4)/3sqr(a^2) by sqr i mean square root. A) a 2/15 B) 1/a 7/4 c) a 7/4 d) 1/ a 2/15

1. Nnesha

$\huge\rm \frac{ 4\sqrt{a^4} }{ 3 \sqrt{a^2}}$ like this ?

2. anonymous

yes

3. triciaal

** 5 not 4

4. anonymous

yes

5. Nnesha

$\huge\rm \frac{ 5\sqrt{a^4} }{ 3 \sqrt{a^2}}$ typo thanks triciaal

6. Nnesha

so you can convert square root to 1/2 exponent $\huge\rm \sqrt[n]{x^m} = x^\frac{ m }{ n }$

and

8. Nnesha

do it and let me know what you get $\huge\rm \sqrt{a^4} = a^\frac{ ? }{ ?? }$

9. anonymous

a 5/4

10. Nnesha

square root so n=2

11. triciaal

above is correct you can also use (rt a ) as a single entity when you divide numbers or variable with the same base subtract the exponents
