a^2\cdot a^3=a^{2+3}=a^5

Why?

a^2=a\cdot a\\\\a^3=a\cdot a\cdot a\\\\a^2\cdot a^3=\underbrace{(a\cdot a)}_{2}\cdot\underbrace{(a\cdot a\cdot a)}_{3}=\underbrace{a\cdot a\cdot a\cdot a\cdot a}_{2+3=5}

Using Euclid's division algorithm prove that : 847,2160 are co-primes
AysviL [449]
Definition of eo-primes or relatively primes: Two numbers are said to be co-prime or relatively prime If their HCF IS 1 Hence to prove 847 and 2160 as co-prime numbers we will find their HCF and which should be 1

New steps to find HCF will be as under

2160 = 847 x 2+ 466
847 = 466 ×1 +381
466 = 381 x 1 + 85
381 =85 x 4+ 41
85 =41 x 2+3
41 =3 x 13+ 2
3 =2 x 1+1
2 =1 x 2+0

Therefore, the HCF=1 Hence, the numbers are co-primes (relatively prime).

Study this table. x y –3 –2 –2 0 0 4 4 12 Which best describes the function represented by the data in the table? linear with a
ss7ja [257]

we can do this by 2 ways

1- by plotting the points on graph and then tracing the points to get shape,

for linear, we will get straight line

for quadratic, we will get parabola

in this case, it is linear as we get a straight line

2- by solving for values of x and y

consider standard linear equation y = mx +c where m is slope and c is constant

by putting given values of x and y we get

y + 2x = 4(answer)

if we consider standard parabola equation

y^2 = 4ax

this equation is not true for given points
