Resiprocal of (-3/7)^2!

USPshnik [31]

Answer:

$\frac{49}{9}$

Step-by-step explanation:

Given

$(\frac{-3}{7})^{2!}$

Required

Determine the reciprocal

If a number is x, the reciprocal is: 1/x

So, the reciprocal of $(\frac{-3}{7})^{2!}$ is:

$\frac{1}{(\frac{-3}{7})^{2!}}$

$2! = 2*1 =2$

So, we have:

$\frac{1}{(\frac{-3}{7})^{2}}$

$\frac{1}{(\frac{-3^{2}}{7^{2}})}$

Evaluate all exponents

$\frac{1}{(\frac{9}{49})}$

Take inverse of 9/49

$\frac{49}{9}$

Hence, the reciprocal of $(\frac{-3}{7})^{2!}$ is $\frac{49}{9}$

Hey can someone help me plz I don't know how to this?

So yes the board is wide enough. The are 10 decimeters in a meter.

What it is asking you to do in the example above is multiply 2.5/23.5 by 1.2 both top and bottom aka the numerator and denominator. This makes it easier to view and divide.

I didn't use this method I just looked at it but give it a try for your answer to B
