0+9=9

1 x 9=9

Step-by-step explanation:

Here, we have to write a kind of equation with 0 and 9

And 1 and 9

So, as to create same result

We know that 0 is the additive identity

Hence, 0+9=9

And 1 is the multiplicative identity

Hence, 1 x 9=9

Therefore, 0+9 and 1 x 9 will give the same result.

Problem Statement:

What is the value of $\frac{5^{4} }{5 ^{6} }$ ?

To solve this problem, we must familiarize ourselves with the concept of exponents and rules that guides them.

Exponents are used by scientists to report higher orders of a number.

Such large and often recurring expression is usually made up of a base and an exponent value.

The exponent value is the power of the base; for example, 4³ has 4 as its base and 3 as the exponent.

Several rules guides solving an exponent, to this problem, the most applicable one is :

$\frac{x^{a} }{x^{b} }$ = $x^{(a-b)}$

$\frac{5^{4} }{5 ^{6} }$ = $5^{4-6}$

= $5^{-2}$

= $\frac{1}{25}$

Therefore the solution is 1 over 25

How many possibe values of w can there be if w is a number between 39 and 56, w is an even number, and w is evenly divisible by

german

Answer: 3

Step-by-step explanation:

The numbers possible to begin with are 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56 (18 options)

Making it only evens brings it down to 40, 42, 44, 46, 48, 50, 52, 54, 56 (9 options)

Then divisible by three leaves 42, 48, 54 (3 options)
