HELPPPPPPPPP i have the most trouble with math what’s the answer??
lakkis [162]

Answer:

Second Option

\frac{5\sqrt{11} +5\sqrt{3}}{8}

Step-by-step explanation:

To simplify the expression you must multiply the numerator and the denominator of the fraction by the conjugate of the denominator.

If you have an expression of the form

a -b then its conjugate will be a + b.

The result of that multiplication will be

a ^ 2 -b ^ 2

Therefore we have the expression

\frac{5}{\sqrt{11} -\sqrt{3}}

By multiplying by the conjugate of the denominator we have

\frac{5}{\sqrt{11} -\sqrt{3}}*\frac{\sqrt{11} +\sqrt{3}}{\sqrt{11} +\sqrt{3}}\\\\\\\frac{5(\sqrt{11} +\sqrt{3})}{(\sqrt{11})^2 -(\sqrt{3})^2}\\\\\\\frac{5\sqrt{11} +5\sqrt{3}}{11 -3}\\\\\\\frac{5\sqrt{11} +5\sqrt{3}}{8}

There are (4^9)^5 ⋅ 4^0 books at the library. What is the total number of books at the library?
seraphim [82]
Do (4^9)^5 first, when an exponent is in a parenthesis with another exponent outside, you multiply them which makes 4^45. Then we multiply 4^0 but this time we add the exponent because there’s no parentheses, which gives you 4^45.
