Describe how (2 ^ 3)(2 ^ - 4) can be simplified . Multiply the bases and add the exponents. Then find the reciprocal and change

tigry1 [53]

Answer:

Add the exponents and keep the same base Then find the reciprocal and change the sign of the exponent .

Step-by-step explanation:

Given the expression (2^3)(2^- 4), we will apply the law of indices below to solve the equation;

$a^m \times a^n = a^{m+n}\\a^{-m} =\frac{1}{a^m}$

Applying this on the given expression;

$(2 ^ 3)(2 ^{-4})$

Step 1: Add the exponents and keep the same base as shown;

$= (2 ^ 3)(2 ^{-4})\\\\= 2^{3+(-4)}\\\\ = 2^{3-4}\\\\= 2^{-1}$

Step 2: Find the reciprocal and change the sign of the exponent

$= 2^{-1} \\= \frac{1}{2^1}\\= \frac{1}{2}$

40=3x+x^2<br><br> How do I find the answer to this

tamaranim1 [39]

Answer:

x = -8, x = 5

Step-by-step explanation:

This can be solved using Factorization method:

$40 = 3x + {x}^{2} \\ \\ \implies \: {x}^{2} + 3x - 40 = 0 \\ \\ \implies \: {x}^{2} + 8x - 5x- 40 = 0 \\ \\ \implies \: x({x} + 8) - 5(x + 8) = 0 \\ \\ \implies \: ({x} + 8) (x - 5) = 0 \\ \\ \implies \: ({x} + 8) = 0 \: \: or \: \: (x - 5) = 0 \\ \\ \implies \: x = - 8 \: \: or \: \: x = 5 \\ \\ x = - 8, \: \: 5$
