Multiplying two digits​

Mathematics
1 answer:
Vika [28.1K]3 years ago
4 0

Answer:

Get a calculator

Step-by-step explanation:

Most of the time for simple math like multiplying 2 digits, it is easiest if you just get a calculator. It saves a lot of time.

If you can't get a calculator then i recommend memorizing some common equations.

For example 10*15= 150

so that if you get 12*15=?, you can easily just add two extra 15's to your answer of 150.

15+15 is 30, and 30+150(from 10*15)=180.

Therefore 12*15=180.

:) Hope that helped!

Expanding logarithmic Expression In Exercise,Use the properties of logarithms to rewrite the expression as a sum,difference,or m
ch4aika [34]

Answer:

\ln x+\frac{1}{3}\ln (x^2+1)

Step-by-step explanation:

Consider the given expression is

\ln (x\sqrt[3]{x^2+1})

We need to rewrite the expression as a sum,difference,or multiple of logarithms.

\ln (x(x^2+1)^{\frac{1}{3}})        [\because \sqrt[n]{x}=x^{\frac{1}{n}}]

Using the properties of logarithm we get

\ln x+\ln (x^2+1)^{\frac{1}{3}}         [\because \ln (ab)=\ln a+\ln b]

\ln x+\frac{1}{3}\ln (x^2+1)        [\because \ln (a^b)=b\ln a]

Therefore, the simplified form of the given expression is \ln x+\frac{1}{3}\ln (x^2+1).

1. Kim's age is twice that of her sister. When you add Kim's age to her sister's age, you get 24. How old is each
Andre45 [30]

Answer:

a) Let Kim's age be k, then Kim's sister's age is k/2

k+\frac{k}{2}=24

b) k+\frac{k}{2}=24

1\frac{1}{2}k=24

k=16

\frac{k}{2}=8

Kim's age is 16 while her sister's age is 8.
