\sqrt{169a {}^2}b {}^(2)Simplify using absolute value as necessary

Question

`\sqrt{169a {}^2}b {}^(2)`Simplify using absolute value as necessary

Answer 1

we have the expression

`\sqrt[\square]{169a^2b^2}`

Remember that

169=13^2

substitute

`\sqrt[\square]{169a^2b^2}=\sqrt[\square]{13^2a^2b^2}`

simplify

`\sqrt[\square]{13^2a^2b^2}=13ab`

answer is 13ab

Part 2

If the expression is

`\sqrt[\square]{16\cdot9\cdot a^2\cdot b^2}`

16=4^2

9=3^2

substitute and simplify

the answer will be

(4)(3)(a)(b)=12ab

answer is 12ab
