Question

3 times (square root of 125 over 5 minus 8)

Answer 1

Parentheses are your friend when typing math equations anywhere. Use them to define function arguments (for example, sqrt, sin, cos, tan, log), exponents, numerators, and denominators. If an exponent, numerator, or denominator includes any math operation, it MUST be enclosed in parentheses.

3(√(125/5) -8) . . . . I have chosen an arrangement that gives a rational result

= 3(√25 -8)

= 3(5 -8)

= 3(-3)

= -9
