Answer:
[tex] - 45.5[/tex]
Step-by-step explanation:
Given that,
[tex]a = 7 \\ b = 2[/tex]
Question :
[tex] \frac{a}{b} - {a}^{b} [/tex]
Let us solve
[tex] \frac{a}{b} - {a}^{b} \\ \frac{7}{2} - {7}^{2} \\ 3.5 - 49 \\ = - 45.5[/tex]
Hope this helps you.
Let me know if you have any other questions :-)
Step-by-step explanation:
= [tex]\frac{7}{2}-7^{2}[/tex]
= [tex]\frac{7}{2}-49[/tex]
= [tex]\frac{7}{2} -\frac{98}{2}[/tex]
= [tex]\frac{-91}{2}[/tex] Or - 45.5
