Question

represent under root 7.8 and under root 9.9 on the number line​

Answer 1

Answer:

if you draw a straight horizontal line and have numbers on it i.e negative and positive and 0 at the centre then it is a number line. now show 4.76 on number line between 4 and 5. Same is the case for √9.9 equals 3.15

Step-by-step explanation:

under root of 7.8

√4 is 2

√9 is 3

now 9-4 is 5

and 7.8 -4 is 3.8

3.8 /5 is 0.76

so √7.8 is nearly 4+.76= 4.76
