Answer:

10017

Step-by-step explanation:

10^(4)-\sqrt(121)+3^(3)+4^(0)

So, 3^3= 27

4^0=1

10^4=10,000

-square 121= -11

So now you got:

10,000-11+27+1

Prove that: 5^31–5^29 is divisible by 100.

ANEK [815]

Answer:

See explanation

Step-by-step explanation:

Consider the expression

$5^{31}-5^{29}$

First, factor it:

$5^{31}-5^{29}=5^{29}\cdot(5^2-1)=5^{29}\cdot (25-1)=24\cdot 5^{29}$

Note that

$100=25\cdot 4$

Then

$5^{31}-5^{29}=24\cdot 5^{29}=6\cdot 4\cdot 25\cdot 5^{27}=6\cdot 100\cdot 5^{27}$

This shows that number 100 is a factor of the expression $5^{31}-5^{29}$ and, therefore, this expression is divisible by 100.

The sum of two numbers is 87. if three times the smaller number is subtracted from the larger number the result is seven. find t

Stolb23 [73]

$\left \{ {{a+b=87} \atop {a-3b=7}} \right.

$

a-3b=7
a=7+3b

a+b=87
(7+3b)+b=87
7+4b=87
4b=87-7
4b=80
b=20

a=7+3b
a=7+3*20
a=7+60
a=67
