Solution

Determine the value of an expression,if s=2/3

\$ 4s^3+1 \$

Given expression

\$ 4s^3+1 \$

Substitute the s value in expression

\$ 4(2/3)^3+1 \$

After simplification we get

\$ 4(8/27)+1 \$

After simplification we get

\$ 32/27 + 1 \$

Convert into improper fraction

\$ (32+27)/27=59/27 \$

Hence the value of the given expression at s=2/3 is

\$ 59/27 \$
