Question

Find the value of z²-2(z-8) for z=10 *
​

Answer 1

Answer:

We will get the value is 96.

Step-by-step explanation:

• As per the question we have to evaluate the given data.

          Given data:- $z=10.$

          To find:- Value of $z^{2} -2(z-8).$

          Solution:-

• To solve the above question we will follow the BODMAS rule.

• BODMAS is an order of mathematic operations.

• It stands for,

           B= bracket

           O= order of power or rules

           D= division

           M= multiplication

           A= addition

           S= subtraction

      Now put the value of z in $z^{2} -2(z-8).$

          $z^{2} -2(z-8)\\=10^{2} -2(10-8)\\=100-20+16\\=100-4\\=96$

Answer 2

Answer:

96

Step-by-step explanation:

Given that,

z = 10

Required to do,

z² - 2(z - 8)

= z² - 2z + 16

= 10² - 2.10 + 16

= 100 - 20 + 16

= 80 + 16

= 96

Ans:- 96
