Question

Find x3 − 2y2 − 3x3 + z4 if x = 3, y = 5, and z = −3.

Answer 1

Find x3 − 2y^2 − 3x^3 + z^4 if x = 3, y = 5, and z = −3.

Answer 2

3^3 - 2(5)^2 - 3(3)^3 + (-3)^4

Answer 3

Yes so now evaluate

Answer 4

\[3^3 = 3 \times 3 \times 3\]
\[2(5)^2 = 2 (5 \times 5)\]
\[-3(3)^3 = -3(3 \times 3 \times 3)\]

\[(-3)^4 = (-3 \times -3 \times - 3 \times - 3)\]

see the pattern here?
