Question

Evaluate the expression. Use y = 5 and z = 3
Yz² - 3 ​

Answer 1

5(3^2)-3
= 42 is the answer

Answer 2

Yz²-3

y = 5

Z = 3

5(3)² -3 =5 × 9 - 3 , we all remember bracket of multiplication , addition and subtraction( BODMAS)

so we'll solve the multiplication first, followed by substraction so 5×9 = 45

45 -3= 42
