Mathematics
1 answer:
ololo11 [35]3 years ago
8 0

Answer:

6x^{13}y^{17}

Step-by-step explanation:

We need to multiply

3x^8y^9.2x^5y^8

We know the exponent rule of multiplication:

x^a y^b . x^cy^d = x^{a+c}y^{b+d}

If the bases are same the powers are added.

So,

=3*2 *x^8*x^5*y^9*y^8\\=^{8+5}y^{9+8}\\=6x^{13}y^{17}

So, the answer is:

6x^{13}y^{17}

four apples and one banana cost £1.40 seven apples and one banana cost £2.00 work out the cost of an apple and the cost of a ban
beks73 [17]

Answer:

  • apple: £0.20
  • banana: £0.60

Step-by-step explanation:

Let "a" and "b" represent the costs of one apple and one banana, respectively. Then the purchases can be written ...

  4a +b = 1.40

  7a +b = 2.00

Subtracting the first equation from the second gives ...

  (7a +b) -(4a +b) = (2.00) -(1.40)

  3a = 0.60 . . . . simplify

  a = 0.20 . . . . . .divide by 3

Using this in the first equation, we have ...

  4(0.20) +b = 1.40

  b = 0.60 . . . . . subtract 0.80

The cost of an apple is £0.20; the cost of a banana is £0.60.
