(3)if 5m÷5 -3=5 5 then find m
(4)The diameter of the corona virus is 0.000000120 m.express the given number in standard form.​

Answer 1

Answer:

(3) 5m÷5-3=55

Step-by-step explanation:

5m÷5-3=55

5m÷2=55

5m=55×2

m=55

Answer 2

Answer:

1 st answer = 20.135135135bar , 2nd answer = 0.9757575758 , 3rd answer = 5 , 4th answer = 1200000000

Step-by-step explanation:

(i) 310 ÷ 37 = 8.3783783784

37×3 = 25.135135135

so , 3-5 = 20. 135135135

(ii) 23/25 = 0.92

35/33 = 1.0606060606

then , 23/25 × 35/33 = 0.9757575758

(iii) 5 2 ÷5 = 5 - 3 = 5

so m = 2

(iv)0.000000120 the standard form is 1200000000
