Y and z are whole numbers y<70 z 60 work out the largest possible value of y and z

a) 12

b) 129

Step-by-step explanation:

a)

For the smallest value of , we gotta figure out the smallest value for w and the highest value for x.

For , once , we conclude that cannot be negative and therefore, .

b)

For the largest value of , we gotta figure out the highest value for y and z.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
