12. Answer :
ab2 - (a + c) ÷ a + (a + b)
Substitute a = 4, b = 6 and c = 8.
4(6)2 - (4 + 8) ÷ 4 + (4 + 6)
Operation Parentheses2 Exponent2 Multiply Divide Subtraction Add Result |
Evaluation = 4(6)2 - (4 + 8) ÷ 4 + (4 + 6) = 4(6)2 - 12 ÷ 4 + 10 = 4(36) - 12 ÷ 4 + 10 = 144 - 12 ÷ 4 + 10 = 144 - 3 + 10 = 141 + 10 = 151 |
13. Answer :
= x2 + 3y3
Substitute x = -1 and y = 2.
= (-1)2 + 3(2)2
Evaluation :
Exponent Multiplication Addition Result |
= (-1)2 + 3(2)2 = 1 + 3(4) = 1 + 12 = 13 |
14. Answer :
= (y3 + x) ÷ 2 + x
Substitute x = 1 and y = 1.
= (13 + 1) ÷ 2 + 1
Evaluation :
Parentheses 1Exponent Parentheses Division Addition Result |
= (13 + 1) ÷ 2 + 1 = (13 + 1) ÷ 2 + 1 = (1 + 1) ÷ 2 + 1 = 2 ÷ 2 + 1 = 1 + 1 = 2 |
15. Answer :
= z3 - (y ÷ 3 - 1)
Substitute y = 3 and z = 7.
= 73 - (3 ÷ 3 - 1)
Evaluation :
1Parentheses 1Division 1Subtraction 1Exponent Result |
= 73 - (3 ÷ 3 - 1) = 73 - (3 ÷ 3 - 1) = 73 - (1 - 1) = 73 - 0 = 243 |
