Write in scienctific notation
.00000758

= 7.58 × 10-6

7.58 x 10^-6

Step-by-step explanation:

Move the decimal 6 times to the right in the number so that the resulting number, m = 7.58, is greater than or equal to 1 but less than 10.

Since we moved the decimal to the right the exponent n is negative. n = -6.

Write in the scientific notation form, m × 10n = 7.58 × 10-6

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
