110

Step-by-step explanation:

Step one- Plug in the value of a &b so the equation should look like this

10 x 9 + 5(6-2)

Step two- Apply the PEMDAS rule so in this case we are going to o the parenthesis. 6-2=4

Rewrite the equation like this 10 x 9+5 x 4

Step three- there are no exponents so we are going to multiply and divide from left to right 10 x 9=90 and 5 x 4 = 20

Rewrite the equation 90+20

Step 4 Add and subtract from left to right

Your final answer is 110

Hope this helped :)

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
