5 0

Answer: 5^10

Step-by-step explanation:

If you’re Talking about exponents, you do what’s in the parentheses first, 5^3×5^2 which will be 5^5 because you are adding exponents when multiplying by the same base. Then you multiply The exponents 2 and 5 because when you are multiplying exponents that are in parentheses you multiply the exponents and leave the base the same.

Ps. I’ve added a picture with the rules, I hope this helps

Lim <br> x → 1 <br> ln(x)/<br> sin(7πx)

mote1985 [20]

$\displaystyle\lim_{x\to1}\frac{\ln x}{\sin7\pi x}$

Note that both the numerator and denominator approach 0 as $x\to1$ , so we can try using L'Hopital's rule.

$\displaystyle\lim_{x\to1}\frac{\lnx }{\sin7\pi x}=\lim_{x\to1}\frac{\frac1x}{7\pi\cos7\pi x}=\lim_{x\to1}\frac1{7\pi x\cos7\pi x}$

The denominator is nonzero at $x=1$ , so the limit is equivalent to

$\displaystyle\frac1{\lim\limits_{x\to1}7\pi x\cos7\pi x}=\frac1{7\pi\cos7\pi}=-\frac1{7\pi}$
