Wasn’t sure how to write this out : - )

amid [387]

we are given

$\frac{\sqrt[3]{7}\sqrt{7}}{\sqrt[6]{7^5}}$

we can write it in terms of exponents

$\frac{7^{\frac{1}{3}}*7^{\frac{1}{2}}}{7^{\frac{5}{6}}}$

Firstly , we will simplify numerator

$\frac{7^{\frac{1}{3}+\frac{1}{2}}}{7^{\frac{5}{6}}}$

now, we can add exponents

$\frac{7^{\frac{5}{6}}}{7^{\frac{5}{6}}}$

we can cancel it

and we get

$=1$ ............Answer

Solve 3^2x-5=81<br> Please show work

Strike441 [17]

Let's solve your equation step by step
(3^2)(x)-5=81
step 1:simplify both sides of the equation
(3^2)(x)-5=81
simplify.
9x-5=81
step 2:Add 5 to both sides.
9x-5+5=81+5
9x=86
divide both sides by 9.
9x/9=86/9
x=86/9
Answer:86/9

Hope this helps!
