Which expression is equivalent to 7 2/3 ⋅ 7 1/4?

dimulka [17.4K]

Answer:

Step-by-step explanation:

Recall that $7^a\cdot 7^b = 7^{a+b}$

So now

$7^{2/3} \cdot 7^{1/3}\\= 7^{\frac{2}{3}+\frac{1}{4}}\\=7^{\frac{8}{12}+\frac{3}{12}}\\=7^{11/12}$

If f and g are continuous functions with f(0) = 2 and the following limit, find g(0). lim_(x->0)[2 f(x) - g(x)] = -3

ladessa [460]

We have by distributivity of limits over sums, and continuity of $f(x)$ and $g(x)$ , that

$\displaystyle \lim_{x\to0} \bigg(2f(x) - g(x)\bigg) = 2 \lim_{x\to0} f(x) - \lim_{x\to0} g(x) = 2 f(0) - g(0)$

Given $f(0)=2$ , it follows that

$2^2 - g(0) = -3 \implies g(0) = \boxed{7}$
