The expression is equivalent to 2 , option C is the right answer.
What is an Expression ?
An expression in maths is a statement that contains , constants , variables and mathematical operators.
The expression given in the question is
[tex]\rm \dfrac { 4^{\frac{5}{4}} * 4^{\frac{1}{4}}} {4^{\frac{1}{2}}}[/tex]
Applying exponent rule
[tex]\rm a^m * a^n = a^{m+n}[/tex]
[tex]\rm \dfrac { 4^{\frac{5}{4} +\frac{1}{4}}} {4^{\frac{1}{2}}}[/tex]
Applying exponent rule
[tex]\rm \dfrac{a^m}{a^n} = a^{m-n}[/tex]
[tex]\rm { 4^{\frac{5}{4} +\frac{1}{4} -{\frac{1}{2}}}[/tex]
On solving the exponents
=(6/4) -(1/2)
=4/4
=1
=[tex]\rm 4^{\frac{1}{2}}[/tex]
= 2
Therefore the expression is equivalent to 2 , option C is the right answer.
