Which equation is equivalent to log^x36=2?
Dennis_Churaev [7]

The equation which is equivalent to \log _{x} 36=2 is x^{2}=36 or x = 6 (\log _{6} 36=2).

<u>Step-by-step explanation:</u>

Given Equation:

           \log _{x} 36=2

As we know, in terms of logarithmic rules, when b is raised to the power of y is equal x:

           b^{y}=a

Then, the base b logarithm of x is equal to y

           \log _{b}(x)=y

Now, use the logarithmic rule for the given equation by comparing with above equation. We get b = x, y = 2, and x = 36. Apply this in equation,

            b^{y}=a

            x^{2}=36

When taking out the squares on both sides, we get x = 6. Hence, the given equation can be written as \log _{6} 36=2

Ripley told his mom that multiplying whole numbers by multiples of 10 was easy because you just count zeros in the factors and p
zhuklara [117]

Answer:

She is right, it won´t always work.

Step-by-step explanation:

Hi, in the examples this tactic works because the first numbers, when multiplied, don´t equal 10 (7x6=42 and 8x7=56). If you multiply both numbers and give you 10, you will have to add another zero to the final number and the trick would crash.

Example:

    200    x       500      =    100,000

(2 Zeros)      (2 zeros)        (5 zeros)

Best of luck.

Solve this plssssssssssss
Kobotan [32]

Answer:

2 x^ (3/2)

Step-by-step explanation:

(x^2+x^2)

----------------

x^1/2

Combine like terms

2x^2

-----------

x^1/2

When dividing exponents with the same base, we subtract

a^b/ a^c = a^ (b-c)

2 * (x^2/ x^1/2) = 2( x^(2-1/2)) = 2 * x^ (3/2)
