(300400)=1210^x

(300 \cdot 400) = 12 \cdot 1 0^{x}

x = 4

Solution steps

(300 \cdot 400) = 12 \cdot 1 0^{x}

Switch sides

12 \cdot 1 0^{x} = 300 \cdot 400

Multiply the numbers:

300 \cdot 400 = 120000

12 \cdot 1 0^{x} = 120000

Divide both sides by

12

1 0^{x} = 10000

Apply exponent rules

x = 4

n^{3} = 1. 5^{n}

3 e^{x + 1} - 5 = 7

1 0^{1 - 2 x} = 11

6 4^{x} = 128

\frac{e ^{x}}{1 + e ^{x}} = 0.9
