Step-by-step explanation: Given expression 7 + 9/4.
Let us simplify given sum of fractions by taking common denominator, we get
[tex]\frac{7}{1} +\frac{9}{4}[/tex]
Common denominator is 4.
Therefore, multiplying top and bottom of 7/1 by 4, we get
[tex]\frac{7\times 4}{1\times 4} +\frac{9}{4} = \frac{28}{4} +\frac{9}{4}[/tex].
We got same denominators,
So, combining top numbers, we get
[tex]\frac{28+9}{4}=\frac{37}{4}[/tex]
We can read 37/4 as 37 divided by 4.
Therefore, 37 ÷ 4.
Let us write 4 as the power of 2.
[tex]4= 2^2.[/tex]
37 ÷ [tex]2^2[/tex]
On comparing c÷a^b and 37 ÷ 2^2, we can see..
