f^3+11g-4hf 3 +11g−4hf, cubed, plus, 11, g, minus, 4, h when f=3f=3f, equals, 3, g=2g=2g, equals, 2 and h=7h=7h, equals, 7.
Alik [6]

Given:

The expression is:

f^3+11g-4h

The given values are f=3,\ g=2,\ h=7.

To find:

The value of the given expression for the given values.

Solution:

We have,

f^3+11g-4h

After substituting f=3,\ g=2,\ h=7, we get

f^3+11g-4h=(3)^3+11(2)-4(7)

f^3+11g-4h=27+22-28

f^3+11g-4h=49-28

f^3+11g-4h=21

Therefore, the value of the given expression is 21.
