Item $2.$ Gilat $-$ Chapter $1$ problem $($see #$3$ and #$5$ below$)-$

hint: use "doc log$"$ at the command window, review each "see also" option and investigate algebraic expressions for square roots.

Add variables that are $3$ characters or more to show that answer instead of simply using "ans" by default.

Make the problems clear by using the disp as needed to print parts$\_$a$,$ parts$\_$b$,$ etc.

Remember to let Matlab do all the math work.

$3.$ Calculate:

a$)\frac{3^{7}log(76)}{7^3+546}+\sqrt[3]{910}$

b$)43*\frac{(\sqrt[4]{250}+23{)}^2}{e^{(45-3^3)}}$

$5.$ Define the variable $x$ as $x=13\mathrm{.}5,$ then evaluate:

a$)x^3+5x^2-26\mathrm{.}7x-52$

b$)\frac{\sqrt[\phantom{2}]{14x^3}}{e^{3x}}$
