Question

please give correct answer​

Answer 1

Step-by-step explanation:

1) three rational numbers between 3 and 4 are 7/2,18/5,19/5. three irrational numbers between 3 and 4 are 2√6,3√2,3√5.

Because a rational number is a number that can be expressed in p/q form where q is not equal to 0.

2)A rationalising factor is a number that converts irrational number into rational number.

so the rationalising factor of 7-2√3 is 7-2√3.

3)By rationalising it's denominator we get the form of

${a}^{2} - {b}^{2}$

. So its denominator is 17.

4)p/q form of a)0.6=2/3

b)0.7=7/9

c)4.7=43/90

d)0.159=36/225

e)4.035=799/198

5)x=2.Because 1/a= a^-1nda^m*a^n=a^m+n.

And if bases are equal then powers are also equal.
