Both can be divided by 6.

6/6 = 1

12/6 = 2

So 6:12 = 1:2

What is the simplified form of the following expression 7(^3√2x)-3(^3√16x)-3(^3√8x)

svlad2 [7]

Answer:

The simplified form of the expression is $\sqrt[3]{2x}-6\sqrt[3]{x}$

Step-by-step explanation:

Given : Expression $7\sqrt[3]{2x}-3\sqrt[3]{16x}-3\sqrt[3]{8x}$

To Simplified : The expression

Solution :

Step 1 - Write the expression

$7\sqrt[3]{2x}-3\sqrt[3]{16x}-3\sqrt[3]{8x}$

Step 2- Simplify the roots and re-write as

$16=2^3\times2$ and $8=2^3$

$7\sqrt[3]{2x}-3\times2\sqrt[3]{2x}-3\times2\sqrt[3]{x}$

Step 3- Solve the multiplication

$7\sqrt[3]{2x}-6\sqrt[3]{2x}-6\sqrt[3]{x}$

Step 4- Taking $\sqrt[3]{2x}$ common from first two terms

$\sqrt[3]{2x}(7-6)-6\sqrt[3]{x}$

$\sqrt[3]{2x}-6\sqrt[3]{x}$

Therefore, The simplified form of the expression is $\sqrt[3]{2x}-6\sqrt[3]{x}$

Which is the solution to 5^x=8^x-7

Nadya [2.5K]

Answer:

x = 30.97 ( to nearest hundredth).

Step-by-step explanation:

5^x = 8^x-7

Taking logs of both sides:-

ln 5^x = ln 8^x

By the law of logarithms:-

x ln 5 = (x - 7) ln 8

x / (x - 7) = ln 8 / ln 5

x / (x - 7) = 1.292

x = 1.292x - 9.044

1.292x - x = 9.044

x = 9.044 / 0.292

= 30.97 (answer)
